Writing your Agent

You write a class that extends Agent.
Overrite setup(). You must add the behaviors you want your agent to have, use addBehavior.
Override takeDown() with your code for shutting down nicely (unregister with DF).
Each behavior you define will get called in the action method to do its thing. It should execute quickly (cooperative multitasking).
Afterwards, the scheduler will can done to check if the behavior should be removed.
Two other Behavior methods--onStart and onEnd--also get called at the obvious times.
You need to fetch any waiting messages yourself from the message queue. You can do so with a blocking blockingReceive or non-blocking receive call.
- You can also use the MessageTemplate class to fetch messages that match a particular pattern from the queue.
